Physics and Linguistics

04.02.2012

Murray Gell-Mann, an American physicist and winner of the 1969 Nobel Prize in Physics, is known for his work in the field of elementary particles and for predicting the existence of quarks. Unexpectedly, he published an article on linguistics last fall, albeit in collaboration with a professional philologist.

They examined the typical word order in sentences in 2011 languages, including dead ones, and concluded that in short phrases of the first human language (judging by the data of archeology, genetics and linguistics, it arose about 50 years ago), the subject came first, then the object and at the end the predicate. For example: "The man killed the bear." In the future, there was an evolution: "A man killed a bear" and (in the most "advanced" languages) "A man killed a bear." However, this evolution applies only to languages ​​with a fixed word order, such as English.

Curiously, Gell-Mann is not the first prominent physicist to become interested in linguistics. The English scientist Thomas Young (1773-1829), who proved the wave nature of light, contributed to the deciphering of Egyptian hieroglyphs.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Engine made of molecules 02.08.2012

PhD student Nick Vukotich and his team of researchers have published a study in Nature Chemistry that revolutionizes modern chemistry. Scientists have been able to prove that molecules bound together can perform mechanical work directly inside solid materials. This may become a milestone in the development of computer technology, since it becomes possible to control the electronic properties of materials at the molecular level. In essence, the phenomenon opens up a new path for the development of molecular machines: from nanorobots to new types of electronics.

The discovery was made during the study of a new material UWDM-1 (University of Windsor Dynamic Material) - a powdered substance that contains rotaxane molecules and a binuclear copper complex. Rotaxane molecules are shaped like a wheel with an "axle" threaded through it. But most importantly, heating the UWDM-1 causes the microscopic wheels to begin to rotate rapidly around their axis. When the material cools, they stop moving. All the details of the tiny engine are so small that they cannot be seen under a microscope, so the fact that the wheels rotate was confirmed using magnetic resonance spectroscopy.

This discovery means that molecules in solid crystalline materials can be manipulated and created from them into solid-state molecular switches and molecular machines based on the mechanical blocking of molecules.
